As a member of the YouGov Panel you will be invited from time-to-time to participate in surveys on topics ranging from politics to painkillers to pensions. Each time you take part in a survey, you will have your virtual YouGov account credited with cash amounts depending on the survey’s length, or you may be entered into a prize draw.
When you reach £50 in your account, YouGov will send you a cheque for that amount.

I understand that some of my friends think its all a con and you get nothing out of it well here is my proof that they do pay out.
